INTERNAL-COMBUSTION ENGINE.

T 0 all whom itmay concern:

Be it known that I, EDWIN B. JONES, a citizen of the United States, residing at Hornell, in the county of Steuben and State therefor.

The primary object of the invention is to provide a novelly constructed rotary valve which will produce an engine of high efficiency, which will be cheap to manufacture,

A simple in construction, and have no springs,

levers, etc., to get out of order.

Another and more specific ob ect of the invention resides in the provision of an engine wherein the intake vand exhaust are controlled by rotating disks having sl f its adapted to register with the intake and ex haust openings, said disks being actuated b worm gears.

\Vith these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my in vention, reference is to be had to the following descrlption and accompanying drawings, in which,

' Figure 1 is a top plan view of an internal combustion engine embodying my 1nvent1on,

the cover plates being removed, Fig. 2 is a similar view, showing one of the cover plates and one of the disk valves removed, and, Fig. 3 is a side elevation, partly in section, the section being taken on the plane of line 3-3 of Fig. 1.

Referring in detail to the drawings by numerals, 1 designates, generally, a four cylinder internal combustion engine, having the crank case 2 and the cylinders 3, 4, 5 and 6. The cylinders are the usual or any preferred construction, having water jacketed heads 7, which are formed with shallow annular recesses 8 in the exterior surfaces thereof. These recesses communicate with semi-cylindrical pockets 9 formed by extensions or projections upon one side of the Specification of Letters Patent.

Application filed January 9, 1913.

Patented Feb. 8, 1916.

Serial No. 741,081. cylinders adjacent the outer ends thereof.

Each of the cylinder heads 7 is provided with an intake port 10 having an exhaust port 11. It will be noted upon reference to Fig. 1, that the ports of each cylinder are 90 apart and that the intake ports of cylinders 3 and 4, and cylinders 5 and 6, respectively, are located in juxta-position to one another. The exhaust ports Ill are all located upon the same side of the longitudinal centers of the cylinders.

A disk valve 12 is positioned within each of the recesses 8 and is formed with an arouate slot 13, which is adapted to register with the corresponding intake and exhaust ports. The disks revolve around the plane outer extremities of hollow cylindrical sleeves 14, the inner extremities of which are externally screw threaded and non-rotatab]y"secured in threaded openings formed centrally/ of the cylinder heads 7Q The pivot members 14 are threaded internally for a portion of their length to receive the spark plugs 15. The disk valves 12 are formed upon their peripheries with the spur teeth 16 for engagement with worm gears 17 positioned within the pockets 9. These gears are rigid with a shaft 18, which car-' ries a sprocket wheel 19 formed on one end thereof. The spur gears .17 are rotated through the medium of asprocket chain 20 engaging a sprocket wheel 21, rigid with the crank shaft 22 and the sprocket wheel 19. The sprocket wheels 19 and 21 are so proportioned as to cause the disks 12 to rotate a quarter of a revolution for every stroke of the piston, or in other words, the crank shaft makes two revolutions to every revolution of the disk valve.

Cover plates 23 are bolted or otherwise secured to each of the cylinder heads so as to protect the valves and gears and retain them in their positions and are formed centrally with apertures receiving the outer plane ends of the pivot sleeves 14, which latter terminate flush with the outer surfaces of' the cover plates. The cover plates are formed with projections 24 which cooperate with the pockets 9 to form cylindrical casings for the gears 17. The cover plates 23 are formed with openings which register with the intake and exhaust ports and exhaust pipes 25 and intake pipes 26 are secured about the respective openings.

When the piston within the cylinder 3 is about to start upon its intake stroke, the end of the slot 13 in the corresponding disk valve will exactly register with the intake opening sothat the piston starts on the intake stroke with a wide open port, which stays thus until the piston has nearly reached the end of said stroke. At the completion of the intake stroke the slot 13 will have passed from registration with the intake port, closing the same, and the ports are arranged for the compression stroke. As before stated, for each stroke of a piston, the corresponding valve moves through a quarter of a revolution so that the ports are properly opened and closed. In Fig. 1 the disk valves are illustrated in positions upon the cylinders 3, 4, 5 and 6, corresponding to the beginning of the intake, compression, exhaust, and power strokes, respectively.

It will be noted from the foregoing description in connection with the accompanying drawings, that I have provided an improved valve. for internal combustion engines which eliminates the use of cam shafts, valve lifters, push rods, valve springs, etc., therefore increasing the efliciency of the engine and producing a mechanically silent 'mechanism. It will alsobe noted that the valves are individually accessible and are also interchangeable so "that when the gear teeth become worn on one side, the valve may be positioned within another cylinder and be rotated in the opposite direction so as tobring the wear upon the other sides of the gear teeth. This interchange of parts is made possible by the fact that the outermost Worm gears 1'? drive in a direction opposite to the inner gears, as clearly shown in Fig. 1.

While I have shown and described my invention embodied in a four cylinder engine, it is to be understood that I do not wish to be limited to this specific use, but may embody the same in an engine of any number valve secured to the cylinder head and hav- Y ing an. opening registering with the opening in the valve and cylinder head, a sleeve having external screwthreads at its inner endfitted in the threaded opening and having a plane external surface at its outer end received within the openings in the valve and cover plate, said sleeve terminating flush with the outer surface of the cover plate and having internal screwthreads at its outer end, and a spark plug removably fitted in the internally screwthreaded portion of said sleeve.

In testimony whereof I atiix my signature in presence of two witnesses.
